Error description

  • In the OpenID Connect (OIDC) Trust Association Interceptor
    (TAI), when the provider_(id).signatureAlgorithm OIDC TAI
    property is set to the value 'none', one of the following errors
    might occur, depending on the WebSphere fixpack installed:
    
    CWTAI2047E: A signing key required by the <null> signature
    algorithm was not available. Signing key is not valid
    
    CWTAI2061E: The OpenID Connect relying party (RP) failed to
    initialize because the value of optional property
    [signatureAlgorithm] is set to [none], which is not one of the
    supported values [RS256, RS512, HS256].

    'none' without error.
    
    The fix for this APAR is targeted for inclusion in fix pack
    8.5.5.23 and 9.0.5.13. For more information, see 'Recommended
